This question is for anyone who has an Islandia with a Merc 240 EFI drive. I am beginning to suspect that I may have a problem with jet drive. According to my instruments the boat speed is about 7-8 MPH when the engine RPMs are 3000. Is that normal or am I correct in assuming that there maybe something wrong with the drive assembly? Lake Conroe is somewhat choppy so I am not sure if that has any effects on the boat performance.

While I was out on the lake yesterday, I noticed something that made me nervous. I was crusing at 4000 rpms and all of a sudden the rpms jumped to 4500. I dropped the throttle back down to idle checked the engine and I didn't see or hear anything out of the ordinary. Later on the same thing happened, I was crusing at 4500 rpms and again the rpms jumped to about 5000.

I did not notice anything unsually when I was slowly throttling up the entire time.

Does anyone have a list of alarms/beep patterns that the Islandia or the Mercury M2 makes when there is an issue?

Yesterday, while I was working on the boat, I turned the key to accessory mode and after a few seconds a constant beeping sound came from the console. Anyone have any idea what it is? Is it a low battery, low oil, or is it a more serious problem?

I want to introduce myself, I have been lurking around this form when I started my boat search. I am the proud owner of a 2001 Sea Doo Islandia. When I started my initial search, I was looking for a 230 Challenger, but I came across the Islandia that I purchased.

I took her out on the water for the first time this past Saturday and I feel like I made the right decision. I currently have the boat stored at a marina in Lake Conroe,Tx.

This is my first jet boat so I would appreciate if anyone has any tips or tricks that they learned, especially about maintaining the jet drive and the 240 EFI motor.
